TI BQ24250RGER

锂离子2A-40°C ~ 85°C（TA）

Overview

The bq24250, bq24251, and bq24253 are highly integrated single-cell Li-Ion battery chargers and system power-path management devices targeted for space-limited, portable applications with high-capacity batteries. The single-cell charger has a single input that operates from either a USB port or an AC wall adapter for a versatile solution.

The battery is charged in four phases: trickle charge, precharge, constant current, and constant voltage. In all charge phases, an internal control loop monitors the IC junction temperature and reduces the charge current if the internal temperature threshold is exceeded. Additionally, a voltage-based, JEITA compatible battery pack thermistor monitoring input (TS) that monitors battery temperature for safe charging is included.
